The largest river on the planet, the Amazon, forms from the confluence of the Solimões (the upper Amazon River) and the Negro at the Brazilian city of Manaus in central Amazonas. At the river confluence, the muddy, tan-colored waters of the Solimões meet the “black” water of the Negro River. The unique mixing zone where the waters meet extends downstream through the rainforest for hundreds of kilometers, and is a famous attraction for tourists from all over the world.

The Paraná River, in the center of the view, has been the principal transportation artery of central South America since the times of early colonization. Consequently, the river gave rise to the growth of port cities such as Argentina’s second city, Rosario (bottom center), now a major industrial center (pop. > 1.1 million). Rosario is the center of a vibrant local agricultural economy—intensive agriculture is visible on the left margin of the view. As such, Rosario is one of the key cities in South America’s MERCOSUR common market (Argentina, Brazil, Paraguay, Uruguay). Other cities have expanded along the river bank, especially northward (for example, Capitan Bermudez, top left).
